To all whom it' may concern.' y

Be it known that lf, RICHARD W. HUBBARD, citizen of the United States, 'residing at Ashtabula, State of Ohio, have invented new and useful improvements the following is a specification.

My invention has to do with means for yieldingly holding coors in a closed position; and it contemplates the provision of simple, compact and ecient means calculated` to retain a door in a closed position against Wind pressure, and yet adapted to release the door when the same is pushed.

or pulled, this with a View of meeting laws and municipal regulations inhibiting the locking of the doors of schools and other public places when persons are gathered in the same. l

YV ith the foregoing' in view, the invention will be fully understood from the following description and claim when the same are read in connection with the drawings, accompanying and forming part oli-this speciication', in which: Figure 1 is a horizontal section taken Vthrough a door and its casing and illustrating my improved door-holding means as properly arranged relative to the same. lig. 2 is af detail perspective view illustrating the plunger of the holding means in -its sleeve or cylindrical casing. Fig. 3 is a similar View of the keeper, showing the preferred proportional height of the same.

Similar letters designate corresponding parts in all of the views or" the drawings,

referring to which:

is a portion of a swinging door. B is a portion of the casing of the door. C is the keeper comprised in my improvements, and D, E and F are the' spring, the plunger, and the sleeve, respectively, of the member adapted to coperate with the -keeper* C is provided with a seat a which is preferably in the form oi a groove,

' of a greater length than the diameter oit' the plunger E in a so as to assure plunger and the out the proportion shown,

keeper when one is not accurately positioned relative to the other.

in the preferred application of my invention the keeper C is carried by the door casing, and is suitably dried `in a recess "t" in the inner side of one upright of the casin the' county of Ashtabula and in Door-Checks, of which the A engagement between the.

is formed in the outer vertical edge of the'60 door, and in said socket is placed the coiled spring l), this arrangement being advantageous inasmuch as when it is desired to' increase the tension of the spring the same may be accomplished spring and placing one or in the bottom of the socket c. lAfter the spring is placed in the socket, the plunger E is arranged with its enlarged inner end e against theouter en d of then the sleeve F is suitably fixed in the socket so as to guide the plunger in its movements and prevent undue outward movenient oit the plunger under the action of the more Washers d sleeve, as indicated by f, and to secure it in the socket through the medium of said thread, and also prefer to kerf the outer end of the sleeve, as indicated by g, so that it may be turned screw-driver into the socket until its outer end is flush with the edge of the door.

With the keeper C and the member that coperates therewith relatively arranged as shown, it will be seen tli'atavhen the door A 85 vis swung to its closed position", the plunger E, Which normally protrudes slightly eyond the outer end of the sleeve F, will ride into the seat a of the keeper,

the door even when the same is subjected to wind pressure, and yet will and permit the door to open when the same is pulled olf-pushed.

rangement described is the preferred one when my improvements are applied to a single door, but that'when desired thezim-4 provements may be arrangedat either the upper end of the door and door casing also, 100

that the latter arrangement is resorted to when my improvements are applied to douf ble doors andy the casing thereof. I would further have it understood that without involving departurefrom the scope of my in- 105 vention, the arrangement may be reversede., the keeper C may` be carried at the outer vertical edge or one of the horizontal edges or' the door and the member that coperates with the keeper Parenteel New. so, 1909. Y

by removing the the spring, and- .fl prefer to exteriorly thread the through the medium of a and when' in said position will prevent casual opening of give inwardly i would have it understood thatlthe armay be carried by one of the upright portions or by one of the'horizontal portions of the door easing.

In addition to the advantages hereinbefore ascribed to my improvements, noted that the same are simple and compact in construction and reliable in operation, and are calculated to enhance rather than detract from the. finished appearance of a door and its casing.

Having described my invention, what I claim and desire to Secure by Letters-'Patent, is:

In means for the purpose described7 the combination with a door and its casing, ot' a keeper carried by the one and having a seat, and a member for cooperating` with the keeper, carried by the other; the said memit will be y ber comprising a coiled spring` arranged in a socket 1n such other, an eXteriorly-threaded sleeve secured by its thread in the socket and having a hert in its outer end, anda plunger disposed in thesleeve and normally protruding beyond the outer end thereof and having an enlargement interposed between the outer end of the spring and the inner end of the sleeve. v

In testimony whereotl I have hereunto Set my hand in presence of two subscribing witnesses.
